Notes: Newly recognized mobility limitation is defined as two consecutive semi-annual reports within 2 years of difficulty walking one-quarter mile or climbing one flight of stairs. Poor performance on the Long Distance Corridor Walk constitutes needing more than 7 minutes to walk 400 meters “as quickly as possible.”
